Turtleneck sweater with a half-zip fastening made of pure 5-gauge cashmere with 3 threads of 2/28 to create a “large braid” stitch that makes the garment very striking, soft, breathable and warm. The enveloping texture of the yarn and inclusion of a metal zip enhances the traditional style of the “large braid” knit, giving the knit a contemporary twist. The fit has regular and comfortable proportions.
